Thanks for the info.
I think she meant many buckets of granules but I will find out.
The family dollar brand 182oz jugs (1.42 gallons) are 6%.
I'm going to help them get straight using my k-2006 but I'm going to either tell her to get one or sell her mine so I can upgrade to the bigger bottle kit! :-)
She's at the end of her liner life also and will be replacing after this year.
I'll report back later on this and will focus on ph and keeping FC high.
